Inventor: DEIBITSUDO AASAA ASUTON
IPC: D21C9/08
Filed: 1993-01-11
Abstract: PURPOSE: To sustain the accumulation of pitch deposit on the fiber cloth or in the paper-making machine that do not continuously come into contact with the treatment water of the paper-making machine by coating the fiber cloth or the machine with a water-soluble or water-dispersible cationic polymer and an anionic aromatic polymer. CONSTITUTION: In the process for sustaining the pitch deposition on the fiber cloth in the drying machine or the apparatus which do not continuously come into contact with the treatment water, these fiber cloth or the machine are coat-treated with a water-soluble or water-dispersible cationic polymer, for example, a quaternary epi-amine polymer with a molecular weight of 1,000-500,000, and a water-soluble or water-dispersible anionic aromatic polymer, for example, lignin, lignin sulfonate, polynaphthalene sulfonate, tannin, sulfonated tannin, and their mixture whereby the accumulation of the pitch deposition can be effectively inhibited or prevented on the drying fiber cloth for the paper drier and other apparatus in the paper-making machine.

Title: Magnetic bubble element
Inventor: SATO TOSHIHIRO
IPC: G11C11/14
Filed: 1986-01-31
Abstract: PURPOSE:To operate a magnetic bubble element with a small area and an excellent characteristic by providing a curved ion implantation transfer path which has at least two corners in a space covering from the high density part of a minor loop and the functional part of a gate. CONSTITUTION:The transfer path is comprised only of symbols G and S in the space covering from the high density part of the minor loop to gate parts 2 and 3 in terms of the magnetic bubble memory element employing the folding-up minor loop of the ion implantation transfer path 1, and folded at 90 deg. and 270 deg. to attain a clank type. A bubble enters the transfer path S from the 90 deg. corner, passes by the 270 deg. corner and enters the transfer path G. Thus the area of the expansion period part from the folding-up transfer path of the minor loop to the gate part is reduced to operate with an excellent characteristic.

IPC: H01L31/111
Filed: 1979-02-19
Abstract: PURPOSE: To provide a device whose light firing sensitivity is high and whose dielectric strength is easily heightened, by connecting a power source across the emitter and collector of a phototransistor integrated with a thyristor coupled to another power source.  
     CONSTITUTION: A p-type layer 2, an n-type layer 1, a p-type layer 3 and an n-type layer 5 are provided continuously to one another on an n-type silicon substrate 1 so that a pnpn-thyristor is constituted and its dielectric strength and current capacity are designed at desired values. A phototransistor is composed of an n-type region 4, the p-type layer 3 and the n-type region 5. A DC power source 6 separate from a power source for the thyristor is connected across the emitter and collector electrodes 10, 11 of the phototransistor so that the anode of the DC power source 6 is coupled to the emitter electrode 10. An Ni-Cd battery or the like is used as the DC power source 6. Since the thyristor is fired by a photocurrent i produced by light 8 irradiated upon the surface 7 of the base 3 to cause a main current I to flow, the light sensitivity of the phototransistor can be heightened independently of the dielectric strength of the thyristor.

Title: Gas-insulated transformer
Inventor: OKUBO HITOSHI
IPC: H01F27/18
Filed: 1985-02-04
Abstract: PURPOSE:To enable the circulation of a refrigerant to be reversed for preventing the accumulation of air bubbles, by providing a motor for driving a pump with a changeover switch for changing over the rotating direction of the motor or with a means for reversing the circulating direction of the refrigerant. CONSTITUTION:A motor 20 driving a pump 7 for circulating a refrigerant is provided with a changeover switch 22 for switching the rotating direction of the motor. Constructing a transformer in this manner, the rotating direction of the motor 20 can be reversed by changing over the switch 22 provided on the motor 20 for driving the pump 7, whereby the circulating direction of the refrigerant also can be reversed. Accordingly, even if microbubbles are accumulated in a refrigerant flow path or in a filter as a result of temporary over-load operation of the transformer, these microbubbles can be removed by reversing the circulating direction of the refrigerant. Therefore, the flow of the refrigerant will not be inhibited and the cooling efficiency will not be reduced.

Title: Dry cell
Inventor: SHINODA KENICHI
IPC: H01M50/124
Filed: 1982-02-10
Abstract: PURPOSE:To prevent any bad influence upon the performance of a dry cell, which might be  caused by heat during manufacturing of the dry cell, by coating both the outer circumference  surface of a zinc can and the periphery of a sealing body, which is provided at the upper end  of said zinc can, with a synthetic-resin coat layer which is hardened by thermal rays. CONSTITUTION:A three-dimentionally-cross-linked hardening resin liquid such as an unsaturated  polyester resin liquid or an unsaturated epoxy resin liquid is mixed with an appropriate  amount of a photopolymerization-initiating agent which produces radicals, such as an ultraviolet-ray-polymerization initiating agent or an electron-ray-polymerization initiating agent. A  coat layer 6 is formed by applying such a mixture to an area extending from the outer periphery of a sealing body 5 to the outer circumference surface and the bottom surface of a zinc  can 1, and hardening thus applied mixture by irradiating thermal rays such as ultraviolet rays  or electron rays. Thus, since the above resin liquid absorbs the thermal rays to accelerate its  own polymerization, and hardens in a few seconds according to the exposure, the coat layer 6  is formed into a strong film. As a result, since the above resin liquid is hardened at ordinary  temperature as mentioned above, there is no thermal influence on the dry cell during its manufacturing. In addition, since the above resin liquid is hardened in an extremely short time, doesn't contain any solvent and is of a mono-liquid type, the manufacturing process can be  shortened, and a mass production method can be carried out.

Abstract: PURPOSE: To obtain an internal force utilizing engine, by forming a cylinder and a main body in a unitary manner, connecting a piston and a piston rod by a piston pin, and connecting pressure receiving plates and the main body and connecting the pressure receiving plates and the piston rod respectively by pins.  
     CONSTITUTION: A piston 3 and a piston rod 4 are connected by a piston pin 5, and pressure receiving plates 7 and a main body 6 are connected together by means of pins 8, 10, 11. Further, a cylinder 1 and the main body 6 are formed in a unitary manner by connecting the plates 7 and the piston rod 4 by reaction pins 9. When a force F 1  is applied to the piston 3 by an article 13, it is divided at the piston pin 5 into component forces F 2  and F 3 . The component force F 2  is acted to the pressure receiving plates 7 via reaction pins 9, so that the plates 7 are rotated together with the main body pivoting about pins 10, 11. On the other hand, when a force F 4  is applied to the cylinder 1 by the article 13, the entire body is rotated pivoting around pins 10, 11. Further, if forces F 1  and F 4  are applied simultaneously, it works in the direction in which the resultant force of F 3  and F 6  is acted.

CONSTITUTION:Between a fixed jaw 31 and movable jaw 32, an upper edge sealing part L of a container C is fed, and an elevating rod 41 descends, and an advance/reverse rod 45 is moved to the right-hand side by a taper part 41a. This movement is transmitted to a movable holder 34 by a pressing spring 57, and the movable holder 34 moves to the right-hand side, and the movable jaw 32 moves to the right-hand side. The movable jaw 32 is pressed to the fixed jaw 31 through the upper edge sealing part L, and the pressing spring 57 is compressed, and the advance/reverse rod 45 keeps moving to the right-hand side. When the descending of the elevating rod 41 stops, the advance/reverse rod 45 also stops. Under this condition, a pressing force, which is equivalent to the force of the pressing spring 57, generates between the fixed jaw 31 and movable jaw 32. By this pressing force, the upper edge sealing part L is pressed and is pressure-bonded.
